full-season

The compound adjective "full-season" is a modern formation from two native English elements. "Full" derives from the Proto-Germanic fullaz, meaning "full," which has retained its core sense of completeness. "Season" entered English via Old French from the Latin sationem, meaning "a sowing," rooted in the verb serere, "to sow." Its meaning broadened from an agricultural activity to denote any characteristic period of the year. Combined, the term logically denotes something that encompasses the complete duration of such a period, commonly applied in contexts like sports ("a full-season ticket") or agriculture ("full-season crops").

Structure: full (complete) + season (period of the year) - full: From Old English full, meaning "complete, entire, abundant." It functions as an intensifying adjective modifying the noun. - season: From Old French seison, meaning "sowing, planting," later "time of year." It functions as the core noun specifying the period.
